AH1-1  
High Dynamic Range Amplifier  
Product Features  
Product Description  
Functional Diagram  
GND  
The AH1-1 is a high dynamic range amplifier in a low-cost  
surface-mount package. The combination of low noise  
figure and high output IP3 at the same bias point makes it  
ideal for receiver and transmitter applications. The AH1-1  
is a specially screened version of the AH1 offering a very  
narrow gain spread from device to device.

The device combines dependable performance with superb  
quality to maintain MTTF values exceeding 100 years at  
mounting temperatures of +85qC. The AH1-1 is available  
in both the standard SOT-89 package and the  
environmentally-friendly lead-free/green/RoHS-compliant  
SOT-89 package.

Applications  
The broadband amplifier uses a high reliability GaAs  
MMIC technology and is targeted for applications where  
high linearity is required. It is well suited for various  
current and next generation wireless technologies such as  
GPRS, GSM, CDMA, and W-CDMA. In addition, the  
AH1-1 will work for other applications within the 250 to 3  
4000 MHz frequency range such as fixed wireless.

2. 3OIP measured with two tones at an output power of +5 dBm/tone separated by 10 MHz. The  
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.  
3. Noise figure can be optimized by matching the input for optimal return loss.
